수동보십시오 graphviz를 \ bin 폴더를 추가 : 나는 다음과 같은 오류가

graph.write_jpg('example1_graph.jpg') 

을 시스템 PATH에.

>>> import pydot 
>>> pydot.find_graphviz() 
{'dot': 'C:\\Program Files (x86)\\Graphviz 2.28\\bin\\dot.exe'} #... 
>>> print pydot.find_graphviz.__doc__ 
""" 
Locate Graphviz's executables in the system. 

    Tries three methods: 

    First: Windows Registry (Windows only) 
    This requires Mark Hammond's pywin32 is installed. 

    Secondly: Search the path 
    It will look for 'dot', 'twopi' and 'neato' in all the directories 
    specified in the PATH environment variable. 

    Thirdly: Default install location (Windows only) 
    It will look for 'dot', 'twopi' and 'neato' in the default install 
    location under the "Program Files" directory. 

    It will return a dictionary containing the program names as keys 
    and their paths as values. 

    If this fails, it returns None.
